Joint estimation of interference frequency offset and time delay in PCMA system by Xue-juan WEI, Yong YANG, Yi-ming GUO, Dong-ling ZHANG

“…For cooperative received high-order modulation PCMA (paired carrier multiple access) signals,joint estima-tion of frequency offset and time delay was proposed.The sequence samples stored locally were used as auxiliary data.Estimation of frequency offset and time delay was calculated by optimizing the objective function,which was obtained from the cross-correlation computation of the auxiliary data and mixed signal,and the optimized process was accom-plished by utilizing two-dimensional search.By setting the threshold of joint estimation,the calculated amount was greatly reduced.Modified Cramer-Rao bound (MCRB) of interference frequency offset and time delay was derived,which provided theoretical basis for performance of the proposed algorithm.Simulation results show that the algorithm has similar performance with existing algorithms,but its complexity is reduced by two-thirds.…”

Blood on the Leaves / Blood on the Roots by Brendan Brown

“…Nietzsche’s account of ‘bad conscience’ is read through the Wynterian and Fanonian concept of ‘sociogeny’ to demonstrate its necessity to Nietzsche’s project of the Great Redeemer. This paper, then, demonstrates a previously undiagnosed influence of Nietzsche on Wynter and the role that anarchy plays in her construction of the ‘human being as praxis’. …”
